This invention relates to the horizontal type of stereotype plate casting machines in which the core is mounted-to" rotate on' the fixed horizontal axis and the back is arranged to move bodily toward and from the core, usually in averticaldirection.

The principal objects of the invention are to provide a construction bywhich the back can be tilted outwardly away-from the core to facilitate andsimplify the insertion of the matrix and its replacement by a new one; to provide-this means in a simple form that involves only a few parts, and to arrange the parts in such position that they can be re turned to casting position without any adjustments or any uncertainty as to the position of the box at casting time. I

Other objectsand advantages'of the invention will appear. hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is afront viewof a casting box constructed in accordance with this invention;

Fig. 2 is an end view of the same shown in casting position; and

Fig.3 is an end view withthe parts positioned for removal or replacement of the matrix.

T have applied the invention to a casting machine comprising a frame 10, a core 11 rotatable on a horizontal shaft 11 carried by the frame 10 and a reciprocating back 12. The back is operated by a crank shaft 13 which receives the power from any desired source and has two crank rods 14 which are connected with the back 12. This connection is shown as made through a pair of eccentric pins 15 having arms 16 thereon and adjusting screws 17 adapted to be adjusted from lugs 18 on the frame through which these screws pass. Adjustment ofthese screws determines the height of the box and secures the perfect fit of the box at both ends against the core and the end rings.

The box is guided to move in a vertical direction by a pair of guides 20 which are pivotecl on the concentric portions of the crank shaft 13 and'are received between-guidcways 21 extending vertically downward from the bottom of the casting box 12. These guides therefore arecapable of turning about the it concentric portion of theshaft13. Normally they are held back by strong springs 22 against adjustable stop screws 23 carried by the frame so that they move exactly tovertical position. They performthefunctionof guidingjthe box as if they were fixed in-this position. However, each one is provided with" a turn-buckle 24 pivotally connected with it and adjustably connected with an arm 25 to which the turn-buckle pivoted. These arms 25 are fixed to a shaft 26 which has an arm 27 swinging'it. The'tur'irbuckle and arm form a toggle which, when straightened out,'locks the guides back in casting position. I

In operation. the back is in the position shown in Figs. land 2. The crank shaft 13 is rotated after the casting of the plate to bring thebox down to allowthe plate to be taken out or dischargedin" any desired way and then returned to casting position. It will be observed that whenever the box is raised to casting position the matrix clamps 28 are engaged-by studs 29 fixedon the'frame 10 andforcedtightly against the boxto hold theedge of the matrix M When the box is lowered this pressure is released but the clamps remain in place; and hold'the matrix while the casting isbeing'removed and the operation isrepeatedover and over.

When it is'desired to replace the matrix,

remove it, or introduceitin the first place, the shaft 13 is turned so that the cranks as indicated inFig. 3, pull the box 12 down so that it clears the core. Now the handle 27 is turned-to the position shown in-Fig.' 3 which swings over the whole structure that is pivoted on the shaft 13 in opposition to thetwo springs 22. Now the matrix can be introduced, replaced, removed, or Inspected and then the handle 27 can be swungback. This brings the casting backdirectly under the rotatable core so that when the shaft 131 is rotated a half revolution; the casting boxwillbe I:

closed ready for receiving the metal.

This invention eliminates difiiculties which are now" presentin -'tl1is type-of casting machine because it makes the insertion and re- Inoval'ofthe matrix sin'iple and easy with no parts in the way to obstruct. At the same time no material complications are introduced Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any pe son skilled in the art without departing from the scope of the invention as expressed in the claims.

Therefore I do not wish to be limited to the details shown, but what I do claim is:

1. In a stereotype plate casting device, the combination with a core, of a reciprocahle concave back cooperating with the core and having means for holding the matrix therein, said back being mounted to swing on a horizontal axis at a distance beyond the convex side of the back to a position at the side of the core for facilitating the positioning of the matrix.

2. In a stereotype plate casting machine, the combination with a core, of a back, means for reciprocating the back, guides for guiding the back to move in straightlines du its reciprocation, said guides being pivotally mounted, whereby the guides may be swung to one side to bring the casting box into a position at the side of the core.

3. In a stereotype plate casting machine, the combination with a core, of a back, a crank shaft, means for connecting the back to the crank shaft for reciprocating the back thereby, guides for guiding the back to move in straight lines during its reciprocation, said guides being pivotally mounted on concentric parts of said crank shaft, whereby the guides may be swung to one side to bring the casting box into a position at the side of the core.

4;. In a casting machine, the combination with a mold part, of a crank shaft, a pair of crank rods connected with the crankshaft and with the mold part for reciprocating the mold part, a pair of guides for said mold part pivoted on the crank shaft, means for swinging said guides about the crank shaft, whereby the mold part will be moved laterally, and yielding means for normally holding the mold part in casting position.

5. In a stereotype plate casting device, the

of and shaft Wlll move the hack toward and from their casting position, and stops for l1mltlng the backward motlon 0f the guides to bring the back to casting position.

6. In a stereotype plate casting device, the combination with a core, of a back, means for operating the back, guides for the back pivotally mounted, toggle levers connected with the guides, and a shaft on which the toggle levers are mounted,whereby the turn of saic shaft will move the guides toward and from their guiding position, said toggles being arranged to hold the guides and back in both ex- .treme positions.

7. I11 a stereotype plate casting device, the combination with a rotatable core, of a back, a crank shaft for operating the back, means for adjusting the distance between the crank shaft and theback, a pair of guides for the back pivotally mounted on the crank shaft, a pair of toggle levers connected with the guides, and a shaft on which the toggle levers are mounted, whereby the turn of said shaft will move the back toward and from their casting position.

8. In a casting machine, the combination with a mold part, of a crank shaft, a pair of crank rods connected with the crank shaft and with the mold part for reciprocating the mold part, and a pair of guides for said mold part pivoted on the crank shaft.

9. In arstereotype plate casting machine, the combination with a core, of a back, means for reciprocating the back, guides for guiding the back to move during its reciprocation, said guides being pivotally mounted, whereby the guides may be swung to one side to bring the casting box into a position at the side of the core.

In testimony whereof Iv have hereunto affixed my signature.
